I feel like shit.
Oh, I had a good time, but I'm paying for it now.
(I now recall why I only drink once a year.)
I can't deal with the vast quantities of alcohol anymore.
In my prime, I could drink all night and be bright-eyed the next morning. (I could do a lot of things in my prime that I don't do now.)
Today I feel like I've been kicked in the head and punched in the stomach at the same time.
Needless to say, this calls for a nap.
